Title: Douglas O'Brien: Innovator in Polyethylene Technology
Introduction
Douglas O'Brien is a notable inventor based in West Chicago, IL (US). He has made significant contributions to the field of polyethylene technology, holding 2 patents that showcase his innovative approach to materials used in cable assembly.
Latest Patents
O'Brien's latest patents include a "Semi-foamed polyethylene molding tape" and a "Method of making cable assembly for use in an antenna element assembly." The semi-foamed polyethylene tape is designed for use in the molding of foamed jacket polyethylene cables. The manufacturing process involves tumble mixing low-density foaming polyethylene, ethylene vinyl acetate co-polymer, and polyethylene color concentrate. The tape is extruded using a thermoplastic extruder equipped with a Maddox mixing screw, which effectively mixes the polyethylene compounds. After extrusion, the tape is quenched, and by controlling manufacturing variables, it is foamed to 40% to 50% of its maximum. Ultimately, the tape reaches 100% maximum foaming during the cable assembly manufacturing process.
